Genome-wide scan of standardized XP-EHH for P. vivax SNPs with minor allele frequency of at least 5% in CMB area. Individual chromosomes are identified by alternate colouring of their SNPs, with high scoring SNPs highlighted, indicating loci most likely to have been under recent positive directional selection. a Using 19 isolates obtained from different continents across the globe as the reference population. Dashed lines indicate the top 1% of XP-EHH values (±0.5%, XP-EHH score >1.7 or <−2.93). b Using 18 isolates from eight Asian countries as the reference population: Cambodia, Malaysia, Thailand, Vietnam, China, Myanmar, Laos, and Indonesia. Dashed lines indicate the top 1% of XP-EHH values (±0.5%, XP-EHH score >1.54 or <−4.68)
